Header Specs:

This header is designed for any tube size up to 2 ¼” and collector sizes up to 4”. All of the tubes are inside the frame. It will fit on big block or small block front motor mounts also motor plates. All of our headers are hand made to order, so we can build them for any engine deck height and for any aftermarket cylinder head in any tube size you need, stepped or not. This header has excellent ground clearance and spark plug access. On our design car we used a Milodon low pro file oil pan #30950 or #30955. The bottom of our header is ¼” higher than the bottom of the pan. Measuring from a stock oil pan we have 2” of room at the top and 3” of room at the bottom of the pan for sump kick outs. With no pan kick out the oil filter will easily drop out the bottom. With a kick out style pan the filter may or may not be accessible depending on the size of the sump kick out under the filter.
This header will fit any stock GM steering box and the DSE 600 steering box. It will fit up to a 9” power brake booster and clutch linkage, but it will NOT fit a factory air conditioning box on the fire wall or column shifter linkage. If you are using a Lakewood style scatter shield you may have to slightly trim the outer edge below the starter area.

The stock front motor mount frame stand on the driver side hangs over the back of the “K” member about ¾”. The top back corner of this frame stand needs to be notched for header room. See attached drawing.

Header Installation:

If the header is built as a pro-tour style, all one piece with collectors welded on, they should be installed as the engine is installed. If the header is built as a race style with individual tubes with slip on collectors then follow this sequence.
Driver side, install tubes #1 and #3 from the top at he same time and start header bolts, do not tighten. If you have a kick out oil pan you may need to raise the engine slightly to get these 2 tubes in. Next install #7 from the bottom and start header bolts. Last install #5 from the top. With all tubes in and header bolts snug but not tight install slip on collectors and bolt in place then tighten all header bolts.
On the passenger side with the starter in place repeat the same sequence, #2, #4, #8 #6.
